MockY Posted March 21, 2011 Share Posted March 21, 2011 The issue is present in either case. The difference is that Xampp suppresses errors in the php.ini file. Either way, the issue is common when you don't enclose indexes in quotes, like when you fetch information from a database for example. So instead of $r[index], you should use $r['index'] Your code will still works however, even with these "errors" present.

Pikachu2000 Posted March 21, 2011 Share Posted March 21, 2011 It may 'work' now, but what if a constant is defined with the same name as an unquoted index? It's also inefficient, as now php has to search for a constant by that name, then decide that none exists, and treat the value as a string. It also generates a notice, whether it's displayed or not, AFAIK.
